WATER-HEATER.

Be it known that I, MAX GREENBERG, citi zen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Water Heaters, of which the following is a specification.

This invention relates and particularly to that class thereof adapted for domestic use, and including a tank in which the water is heated and from which it may be drawn by the usual service pipes.

The object of the invention is to provide a construction in which the water will be rapidly heated, the gas burner, by means of -which the water is heated, being located in a conical recess under-the tank, and connected to the chimney by means of a flue which extends through the tank, whereby the products of combustion are utilized to heat the water in the tank as they flow through the flue.

The invention is illustrated in the accompanying drawings, in which igure 1 is a perspective view paratus. broken of the ap- Fig. 2 is a similar view partly away and in section.-

Referring specifically to the drawings, 6

' From the'apex-of the also the tank an indicates a hot water tank of common construction, except as otherwise hereinafter indicated, This tank has a cold water inlet 7 and a hot water outlet 8, and it is supported upon a stand 9. The bottom of the tank is raised above the lower end of the shell and said bottom is conical, as indicated at 10, forming a conical recess which receives the heating vessel and the gas burner. conical bottom a pipe ll extends u wardly and centrally through 5 out at the top thereof, and may be extended as at 12 to a chimney. A water heating vessel 13 is located within conical recess, and it consists of a series of circular pipes connected by short vertical risers 14, the pipe rings being progressively smaller in size toward the a conical vessel. The lowest ring is promay be drawn oil has an opening 17 the water space of the thereto, but aifords which connects with tank at the bottom Specification of Letters Patent.

water the tank may be circulated into the vessel. The to ring is connected to two upwardly exten ing pipes 18 which extend through the flue l1, and these pi cs 18 are joined by the union 19 to a sing e pipe 20 which extends above the ,top of the tank and is connected by tee and cross pipes 21 to the outlet pipe 8 and to a branch 8 which enters through the top of the tank.

r burner 22, conical in shape, fits within or under the vessel 13, being supported by brackets 23 fixed to the shell of the tank near the lower edge thereofl. The burner is located directly under the vessel and serves to heat the Water therein and also to heat of the products of combustion with the conical bottom 10 of the flue 11 which, as said before, extends upwardly through the center of thetank. The heat. generated by the burner is therefore applied to a full extent with which the water is in contact, and so is utilized to a maximum degree. A water circulation takes place'from the tank and through the opening 17 into the vessels, and thence upwardly through the pipes 18 to the union 19 .where its velocity is somewhat checked by the conflict of force, and the water then rises through the pipe 20 and thence through the pipe 21 to the pipes 8- and 8 The side wall of the tank is conveniently provided with a door 24, having a window of mica therein, through which the burner can be seen and lighted.

I claim:

A water heater comprising a tank having a vertical flue throu h the same, a Water heating vessel at the ottom of the flue and connected to the lower-end of the tank, a plurality of upright pipes extending upward'l from the vessel, in the flue a sin le pipe ocated in the upper part of the us and connectedby a union to said pipes-and leading into the upper end of the tank, and a burner under the vessel. 1

In testimony whereof I do afiix my signature, in presence of two witnesses.
